  Selective Kainate Receptor (GluK1) Ligands Structurally Based upon 1H-Cyclopentapyrimidin-2,4(1H,3H)-dione: Synthesis, Molecular Modeling, and Pharmacological and Biostructural Characterization

  摘要：

  The physiological function of kainate receptors (GluK1-GluK5) in the central nervous system is not fully understood yet. With the aim of developing potent and selective GluK1 ligands, we have synthesized a series of new thiophene-based GluK1 agonists (6a-c) and antagonists (7a-d). Pharmacological evaluation revealed that they are selective for the GluK1 subunit, with 7b being the most subtype-selective ligand reported to date (GluK1 vs GluK3). The antagonist 7a was cocrystallized with the GluK1 ligand binding domain, and an X-ray crystallographic analysis revealed the largest flexibility in GluK1 ligand binding domain opening upon binding of a ligand seen to date. The results provide new insights into the molecular Mechanism of GluK1 receptor ligand binding and pave the way to the development of new tool compounds for studying kainate receptor function.

  Fluorinated oligopeptides, especially those having 4,4-difluoro-2-amino butyric acid at the C terminus, may be effective inhibitors of hepatitis C virus NS3 protease. Examples of hexapeptides of the invention, optimized for binding in the S1 specificity pocket of the enzyme, may display IC 50 s at the sub-micromolar level. Embodiments of tripeptides of the invention, having a keto-acid group at the C-terminus are, likewise, potent inhibitors of NS3 protease.

  氟化寡肽，特别是具有C端的4,4-二氟-2-氨基丁酸的寡肽，可能是乙型肝炎病毒NS3蛋白酶的有效抑制剂。该发明的六肽示例，经过优化以在酶的S1特异性口袋中结合，可能在亚微摩尔水平显示IC50。同样，该发明的三肽实施例，其C端具有酮酸基团，也是 蛋白酶的有效抑制剂。

  Some N-3-substituted analogues of willardiine such as 11 and 13 are selective kainate receptor antagonists. In an attempt to improve the potency and selectivity for kainate receptors, a range of analogues of 11 and 13 were synthesized with 5-substituents on the uracil ring. An X-ray crystal structure of the 5-methyl analogue of 13 bound to GLU(K5) revealed that there was allowed volume around the 4- and 5-positions of the thiophene ring, and therefore the 4,5-dibromo and 5-phenyl (67) analogues were synthesized. Compound 67 (ACET) demonstrated low nanomolar antagonist potency on native and recombinant GLU(K5)-containing kainate receptors (K-B values of 7 +/- 1 and 5 +/- 1 nM for antagonism of recombinant human GLU(K5) and GLU(K5)/GLU(K2), respectively) but displayed IC50 values > 100 mu M for antagonism of GLU(A2), GLU(K6), or GLU(K6)/GLU(K2).
• The Design and Enzyme-Bound Crystal Structure of Indoline Based Peptidomimetic Inhibitors of Hepatitis C Virus NS3 Protease

  The design of a series of peptidomimetic inhibitors of the hepatitis C virus NS3 protease is described. These inhibitors feature an indoline-2-carboxamide as a novel heterocyclic replacement for the P3 amino acid residue and N-terminal capping group of tripeptide based inhibitors. The crystal structure of the ternary NS3/NS4A/inhibitor complex for the most active molecule in this series highlights its suitability as an N-terminal capping group of a dipeptide inhibitor of the NS3 protease.
